CHARLES REINAS, OF PHILADELPHIA, PENNSYLVANIA.

SPINDLE-SUPPORT FOR LOOMS.

Specification of Letters Patent.

Patented Dec. so, 1919.

Application filed September 20, 1919. Serial No. 325,271.

To all whom it may concern:

Be it known that I, CHARLES REINAs, a citizen of the United States,residing at'the city of Philadelphia, county of Philadelphia, and Stateof Pennsylvania, have invented certain new and useful ImprovedSpindle-Supports for Looms, of which the following is a specification.

Generally stated this invention has relation to loom shuttle boxes andhas more especial relation to a support for the picker spindle thereof.

It is customary in certain looms of standard make to attach a spindlesupport to a shuttle box by means of two bolts and to vertically tap thesupport to accommodate a bolt for rigidly securing the picker spindlewith respect to the support. Practice dictates that the constantimpinging of a picker stick, upon its return stroke, against a supporttends to jar loose such bolt. F urther the picker bufier requiresrepeated replacement, necessitating each time that such bolt beloosened. The repeated loosening and tightening of such bolt has thetendency to so Wear the threads of a tap, which has in practice but fewthreads, that in a short time the entire support must be discarded,although otherwise perfectly good.

The leading object of the present invention is to overcome the aboverecited disadvantageous features whereby the life of a support ismaterially increased without adding to the manufacturing cost thereof. Afurther object is to provide an improved construction which is readilyadapted to existing types of supports whereby the same,

when no longer useful in their original state,

may be easily-changed in accordance withv the invention at slightexpense.

The invention consists of the improvements hereinafter described andfinally claimed.

The nature, characteristic features and scope of the invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof, and in which Figure1, is a. view in rear elevation, of a portion of a shuttle boxconstruction, illustrating the application thereto of a spindle supportembodying features of the invention.

Fig. 2, is a view in section taken upon the line 22 of Fig. 1, and

Fig. 3, is a view in section taken upon the line 3-3 of Fig. 1, thespindle being omitted.

In the drawings 10 designates so much of a shuttle box structure as isnecessary to an understanding of the invention. Fixed to an uprightthereof is a member 11 for accommodating one end of the picker spindle12 and rigidly clamped to the other upright thereof in the support ofthe invention. Such support comprises a body portion 13 provided with anangular extension 11 against the fiat face of which is adapted to abut,upon its return stroke, a picker stick 15. The body top is provided witha laterally disposed boss 16, which is bifurcated as at 17 and isprovided with longitudinally disposed apertures to receive a spindleend. The rear wall of the bifurcated portion is inclined as at 1819 fora purpose to presently appear and is provided with alaterallydisposed'bolt hole 20 which passes entirely through the body 13 andcommunicate's with the bifurcated portion at the intersection of saidinclined walls 1819. Adapted for passage through such hole and throughan upright of the shuttle box is a bolt 21 provided with a head 22having an opening 111 the boss so as to receive the end of said spindle.A nut is provided with the bolt end for drawing the head toward theinclined walls 18-19 which provide clear: ance for said head in orderthat the spindle and support may be rigidly clamped with respect to theshuttle box. An additional bolt 23 is present to assist in securing thesupport to the shuttle box.

The support as above described covers a construction embodying a supportas newly manufactured. In the case of remodeling a worn support of theold type the procedure is as followsz-In such case the boss 16 is solidand has a spindle opening entirely therethrough. Passing through theboss top is a vertical tap communicating, with such opening foraccommodating a screw for locking the spindle end to place. I first cutaway the solid boss to form a forked boss thereby eliminating the tappedportion. The rear wall of the body 13 of the old type, adjacent the topthereof, is horizontally tapped so thata bolt may be screwed to place tosecure the support to the shuttle box. This tapped portion is in thesame plane with but at right angles to the spindle. I next drill throughthe tapped portion to provide a bolt hole which communicates with thenewly made forked por tion for accon'imodating the aforesaid bolt 21.Thus remodeled the support is a duplicate of the aforesaid newlymanufactured support. It is thus apparent that the invention isapplicable to old and new supports; is inexpensive to manufacture; isefficient in securely clamping a spindle with respect to a supportand'requires but two securing devices one of which functions in twocapacities.

It will now be apparent that I have devised a novel and usefulconstruction which embodies the features of advantage enumerated asdesirable in the statement of the invention and the above descriptionand while I have in the present instance shown and described thepreferred embodiment thereof which has been found in practice to givesatisfactory and reliable results, it is to be understood that the sameis susceptible of modification in various particulars without departingfrom the spirit or scope of the invention or sacrificing any of itsadvantages.

What I claim is:

1. In combination a shuttle box, a picker spindle, a support for thespindle and means including a member which engages around the spindledetachably interlocking said spindle and support with respect to theshuttle box. v

2. In combination a shuttle box, a picker spindle, a support for thespindle and means including an eye-bolt, the eye of which engages aroundthe spindle, detachably interlocking said spindle and support withrespect to the shuttle box.

3. In combination a shuttle box, a bracket having a bifurcated lug andan apertured body portion, an eye-bolt the head of which is accommodatedby said bifurcated portion passing through the said aperture and shuttle box frame, picker spindle passing through said lug and eye-bolt anda nut drawing the bolt to place thereby clamping the spindle and bracketwith respect to the shuttle box.

4. In a device ofthe character stated, a shuttle box, a bracket providedwith a bifurcated portion theears of which are longitudinally aperturedfor spindle reception said bracket beingalso provided with a bolt holeat right angles to said apertures and in communication with saidbifurcated portion, an eye-bolt for passage through said bolt hole andshuttle box the head of which is accommodated by said bifurcated portionand the upper portion of the shuttle box being engaged by saidbifurcated portion and a spindle adapted to pass through said aperturesand the eye of said bolt and a nut drawing said eye-bolt to place. 7 I

In testimony whereof, I have hereunto signed my name. i
